| Summary: | Background. Despite the high modern level of science and technology development, the problems of physical
measurements remain relevant due to extreme operating conditions of primary measuring instruments (sensors),
which take place in the rocket-space technology, including the problems of measuring displacements. he development
of a displacement sensor operating at high temperatures of up to 600 °C imposes restrictions on the materials and wires
used to manufacture inductor coils, due to the fact that there are few materials that are sufficiently strong to withstand
such high temperatures (ceramics, seals). Materials and methods. Methods of integral and differential calculus, theory of
electric circuits and electromagnetic field were used to solve the tasks. A computer-aided design system was used in the
design of sensor structures AutoCAD. Results. As a result of the conducted work on the development of a linear displacement
sensor, a large technological reserve was obtained for further work on the creation of high-temperature displacement
sensors with different measurement ranges for the products of rocket and space technology.
